Upsilon Photo-Production off Proton in QCD Inspired Model

Based on the generalized vector meson dominance model in QCD, we study photoproduction of vector meson T off the proton by use of the QCD inspired model in which the contributions from quark-quark, gluon-gluon, and quark-gluon interference term to observable are taken into consideration. Calculations are performed for total cross section σtot, differential cross section dσ/dt, ratio of the real part to imaginary part of forward scattering amplitude ρ, and nuclear slop parameter function β. The mediators of interactions between projectiles （the quark and antiquark pair fluctuated from the real the photon） and the proton target （three-quark system） are the tensor Glueball and Odderon instead of using the usual Pomeron exchange. The theoretical predictions for σtot （s） are consistent with the experimental data within error bars of the data. The data for dσ/dt, ρ, and β are urgently needed.

Photoproduction of Vector Meson φ off Deuteron in QCD Inspired Model

Based on the quark-gluon contents of nucleon and strongly believing that the force mediators,Pomeronand its counterpart in the conventional approach of Regge theory,for high energy diffractive process would be the tensorglueball and Odderon respectively,we discuss photo-production of vector meson φ off the deuteron at energy less than 3GeV in the QCD inspired model in which the quark gluon degrees of freedom and glueball,Odderon exchange are takeninto account.A calculation is performed for γ + D →φ + D,and the theoretical predictions of the differential crosssection dσ^(γD)) /dt,are presented and compared with available experimental data.Our QCD inspired model reproducesdata quite well in the whole range of the experimental measurements up to |t| ■0.4 GeV.Our results can be used toextract γn→φn data,which cannot be measured in experiment.

Genetic relationship of rapeseed yield-related traits revealed by elite lines under multiple environments

To provide a theoretical basis for further improvement of Brassica napus yield, additive dominance with additive - by - additive epistatic effects （ ADAA） genetic model and a 6 X 8 partial dial- lel cross design were used to analyze the genetic effects and correlations of five yield related traits of 14 excellent Brassica napus parental lines and their 46 and F2 populations. The results showed that silique density （SD） , siliques per plant （SPP） , seeds per silique （SPS） and thousand - seed weight （TSW） exhibited not only additive and dominant effects, but also significant epistatic effects. The dominant effects of all five yield - related traits were obviously greater than their additive effects and epistatic effects. Yield per plant （YPP） showed significant genetic correlation with SD, SPP and SPS, and the main component of the genetic correlation was the dominance correlation. SPP and SPS both showed a significant negative correlation with TSW. The SD of rapeseed was genetically correlated with all three components of yield to a certain extent, and there were different components of genetic effects positively correlated with the three yield components, indicating that SD is a potential trait to reconcile the conflict between TSW and SPP as well as SPS.

Research on pricing,service and logistic decision-making of E-supply chain with‘Free Shipping’strategy

Considering the cost of logistic service and the‘Free Shipping’strategy,two models of E-supply chain,respectively dominated by e-commerce platform or manufacturer are constructed,and the optimal decisions for each model is calculated in this paper.The research indicates that:the sales price is lower and the profit of manufacturer is higher in the mode dominated by manufacturer.On the other hand,the platform’s service-level is lower and the profit of platform is higher in the mode dominated by dominant platform.Further,the sales price,platform’s service and platform’s profit will increase with the growth of commission and decrease with the service cost elasticity coefficient.Contrarily,the profit of manufacturer will decrease with the growth of commission but increase with elasticity coefficient.And,the logistic price and profit of logistic enterprise are higher in the mode dominated by manufacturer,moreover,they will decrease with the growth of commission.

Extraction of Spatial-Temporal Features forVision-Based Gesture Recognition

One of the key problems in a vision-based gesture recognition system is the extraction of spatial-temporal features of gesturing. In this paper anapproach of motion-based segmentation is proposed to realize this task. The directmethod cooperated with the robust M-estimator to estimate the affine parametersof gesturing motion is used, and based on the dominant motion model the gesturingregion is extracted, i.e., the dominant object. So the spatial-temporal features ofgestures can be extracted. Finally, the dynamic time warping (DTW) method isdirectly used to perform matching of 12 control gestures (6 for 'translation' orders,6 for 'rotation' orders). A small demonstration system has been set up to verify themethod, in which a panorama image viewer can be controlled (set by mosaicing asequence of standard 'Garden' images) with recognized gestures instead of the 3-Dmouse tool.
